Antifungal drugs used to treat an unusual infection known as mucormycosis, or "black fungus," are in short supply in many Indian states.

Amphotericin B, which is produced by a number of Indian companies, is also available on the black market.

As the number of cases of mucormycosis rises, there are several emergency appeals for the drug on social media.

The infection may have been caused by the use of steroids in chronically ill Covid patients, according to doctors.

Mucormycosis is a fungal infection caused by mucor mold, which can be found in soil, seeds, manure, and rotting fruits and vegetables.
